Even tho it's early in the century, it might well be the longest eclipse of the century. I imagine that the calculations to predict eclipses and their duration would be relatively straightforward by modern standards. You probably wouldn't even need to take relativity into account.

Not necessarily.

I can imagine a thin film of black carbon absorbing the laser pulse and converting it into heat right on the lens. Iâ(TM)m not sure what theyâ(TM)re made of, but I do hope the research includes the possibility of melting. Spark plugs are made of ceramic instead of glass for a reason as it has superior heat and electrical insulation properties.

The laser plugs in TFA are modified sparkplugs. They just removed the core, cut off the ground electrode, and put lenses in place.

C4 and other explosives use a carefully controlled combination of pressure and temperature. In fact, those explosives can be set alight, and used to cook dinner, because the spark isn't what detonates them.

The problem with cooking dinner on burning C4 is putting it out. It burns nice and slow and even, great for cooking. But let me tell you: don't try stomping it out with your boot when you're done!
